According to researchers, Ebola virus can persist in the body fluids of the patients. In a study conducted by a team of researchers from the Institute for Development and Research in France, sample of body fluids (tears, vaginal fluids, semen and saliva) were taken from 450 survivors in the hospitals in Guinea.
Researchers used detection of ribonucleic acid (RNA) and molecular biology techniques involving the polymerase chain reaction (PCR) to detect the presence of the Ebola virus in the survivors. The virus was detected in 10 samples taken from eight men even after 9 months of recovery. It was also observed that the persistence of the virus decreased with time. In most cases the virus was not found after a period of about 12 months.
The researchers also recommended the survivors to use condoms in the following months of recovery. They also stressed on monitoring the health of the patients in order to restrict the spread of the epidemic, reducing the risks thereby.
